RICHARD'LAWA, or NEW YORK, N. Y.

COMBINATION GAS-RANGE.

Application filed July 12, 1919.

To all whom, it may concern:

Be it known that I, RICHARD LAWA, a citizen of Czecho-Slovakia, and a resident of New York city, in the county of Bronx and State of New York, have invented new and useful Improvements in Combination Gas-Ranges, of which the following is a specification.

My invention relates to improvements in combination gas ranges for kitchens and like places, and it consists in the combina tions, arrangements, and constructions herein described and claimed.

An object of my invention is to provide a combination gas range, so constructed and arranged that it may be quickly converted into a work-table, and in which provision is made for the employment of a variety of devices, designed to be used in cooking op erations, and interchangeable in positions, in order that a variety of cooking operations may be performed in a relatively small space.

My invention has for a further object the provision of a device of the above character which is simple as well as strong and durable in construction, may be manufactured at small cost and is highly convenient and serviceable in practical use.

One of the many possible embodiments of the invention is illustrated in the accom panying drawings forming part of this application, and in which Figure 1 is a view in perspective of a range made in accordance with my invention, parts of the structure being shown in broken lines.

Fig. 2 is a cross-section, taken on the line 2-2 of Fig. 1.

Fig. 3 is a perspective view of the structure as it appears when'converted into a work-table.

Fig. 41 is a view in front elevation of the structure shown in Fig. 1, all the parts being, however, in full lines.

Fig. 5 is a cross-section, taken on the line 5--5 of Fig. 3.

Fig. 6 is a top plan view with parts in section.

Fig. 7 is a perspective view, partly in section, showing a method of arranging various parts.

Fig. 8 is a cross-section, taken on the line 8-8 of Fig. 7.

In the present embodiment of the invention, I employ a rectangular frame, made Specification of Letters Patent. Patented May 18, 1920.

spaced-apart parallel rails 16, upon which are secured the gas burners, herein shown to consist of circular burners 17, alined by pairs transversely of the frame, and of a longitudinal burner 18 also disposed transversely. o

The rear plate 11 and the end plates 12 13 are made of greater depth than the front plate 10; and the said end plates are cast with inwardly projecting bottom ledges 19,

for the reception and support of a work plate 20, whose dimensions are such as to permit it to be placed on the ledge 14 within the frame (Fig. 3), when it is desired to convert the range into a work-table. When it is desired to use the range for cooking purposes, as will be presently described, the work plate 20 is removed from the ledge 14 and stowed away on the ledges 19; it being observed that the parts are so arranged that the ledge 14: supports the plate over the burners, while the ledges 19 support the same under the burners.

The frame so constructed is supported upon legs as 21, of which there are four in number, one secured to the frame under each corner thereof. For purposes of simplicity and stability, these legs are preferably made of angle-iron, and they are connected and braced by the longitudinal and transverse rails 22 and 23, also made of angle-iron and on which is disposed a shelf 24 for the convenient support of cooking utensils, when not in use.

Attached to and projecting forwardly from the end plates are brackets 25, designed to support a gas pipe 26, which may be connected with a suitable source of gas supply. Leading from the pipe 26 are branch pipes 27 which connect with the burners-one pipe for each burner. Associated with each branch pipe is a valve 28 through which theflow of gas is controlled.

As best shown in Fig.- 1,1 provide for the support of cooking utensils, a grate 29, adapted to be set upon the ledge 14 within the frame, the same being of a very simple and inexpensive construction, consisting of spacedly connected parallel bars 30, which extend transversely of the frame. This grate is preferably designed to occupy only one-half the space within the frame, the remainder of the space being divided between the baking plates 31 and 32, which also rest upon the ledge 14. These plates are designed to be used as griddles, on which to bake the so-called butter cakes, wheat cakes and the like. They may also be employed as a support for a heat conserving pan 33; and to this end they are provided with a plurality of apertures to permit the heat to rise in columns uninterruptedly therethrough. Thus the plate 31, which comes substantially over the longitudinal burner 12, is preferably provided with elongated apertures 34, while the plate 32 is provided with circular apertures 35.

The heat conserving pan 33 has its base portion 36 divided into two longitudinal compartments (not shown), designed to receive food which is to be cooked, or which, when cooked, is to be kept in a warm state until served. Rising from the base and inclosing the compartments are the arcuate casings or tops 37 38, each similarly made of two parts 39 and 40, of which the parts 39 are permanently secured to the base, while the parts 40 are pivoted to the parts 39 as at 41 on the outer and opposite sides thereof. The parts 40 are made large enough to telescope the parts 39 when moved rearwardly about their pivots. Access may be had, therefore, to either compartment without opening the other one.

As best illustrated in Fig. 7, I also provide a pan 42, open at its top and designed to be placed on the grate 29 and to contain water, in which may be set any suitable receptacles as 43 containing food to be cooked or kept warm.

To the outer rear ends of the end plates 12 and 13 are secured the uprights 44 and these parts, when removed. Moreover, the

structure may be quickly converted into a worktable by placing the work plate 20 upon the ledge 14. In homes and restaurants having small l :itchens,where the cooks have only a limited space within which to work, the advantages of my improved range will be apparent.

Having thus described my invention, what I claim is In a gas range, the combination of a leg supported rectangular frame consisting of front and rear side plates and connecting end plates, the front side plate being of less depth than the other plates, the end plates being formed with inwardly projecting ledges in a plane below the front side plate, an inwardly projecting upper ledge formed on the frame all around just below its top edge, ledges and connecting rails carried by the frame in a plane between said end ledges and said upper ledge, gas burners disposed on said connections, a table-board engageable either with said end plate ledges below the burners or with said upper ledges over the burners, and devices by means of which cooking operations may be elfected'engageable upon the upper ledge and interchangeable as to position.

In testimony whereof I have signed my name to this specification.

RICHARD LAWA.
